A Study of the Safety and Pharmacokinetics (PK) of MEHD7945A in Participants With Locally Advanced or Metastatic Epithelial Tumors
- Registration Number
- NCT01207323
- Lead Sponsor
- Genentech, Inc.
- Brief Summary
This is a Phase I, multicenter, open-label study of MEHD7945A in participants with incurable, locally advanced, or metastatic epithelial malignancies that have progressed despite standard therapy or for which no standard therapy exists. The study will be conducted in two stages: a dose escalation stage and an expansion stage. The dose-escalation stage is designed to evaluate the safety, tolerability, and PK of MEHD7945A administered (at five dose levels from 1 to 30 milligrams per kilogram \[mg/kg\]) every 2 week (Q2W). An expansion stage will be initiated after establishment of maximum tolerated dose (MTD) in dose escalation stage. Participants with refractory or recurrent metastatic colorectal cancer (CRC), non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), and pancreatic cancer will be enrolled in an expansion stage to better characterize the safety, tolerability, PK and preliminary assessment of the anti-tumor activity of MEHD7945A.

Group Intervention Description Dose Escalation (MEHD7945A) MEHD7945A Participants will receive intravenous (IV) infusion of MEHD7945A in escalating doses Q2W until MTD is reached or up to disease progression as determined by the investigator, intolerable toxicity, withdrawal of consent, or death, whichever occurs first. Approximately 5 dose levels between 1 and 30 mg/kg will be evaluated. Dose Expansion (MEHD7945A) MEHD7945A Participants will receive IV infusion of MEHD7945A Q2W at or below the MTD (decided from dose escalation part) up to disease progression as determined by the investigator, intolerable toxicity, withdrawal of consent, or death, whichever occurs first.
